Control device

Abstract

A control device for controlling a host vehicle including: a processing circuitry configured to, when another vehicle traveling in a opposite direction to the host vehicle and having a possibility to collide with the host vehicle is detected in front of the host vehicle, execute an out-of-vehicle notification using a headlight based on a distance between the host vehicle and the another vehicle. When the distance is equal to or smaller than a first threshold and equal to or larger than a second threshold that is smaller than the first threshold, the processing circuitry executes the out-of-vehicle notification, and when the distance is smaller than the second threshold, the processing circuitry does not execute the out-of-vehicle notification or executes the out-of-vehicle notification with a notification intensity lower than that when the distance is equal to or smaller than the first threshold and equal to or larger than the second threshold.

What is claimed is: 
     
       1. A control device for controlling a vehicle that includes an external sensor configured to acquire surrounding information on a host vehicle and a headlight configured to illuminate ahead of the host vehicle, the control device comprising:
 a processing circuitry configured to, when another vehicle traveling in an opposite direction to the host vehicle and having a possibility to collide with the host vehicle is detected in front of the host vehicle based on the surrounding information acquired by the external sensor, execute an out-of-vehicle notification using the headlight based on a distance between the host vehicle and the another vehicle, wherein 
 when the another vehicle is detected in front of the host vehicle and a travel speed of the host vehicle is equal to or larger than a predetermined value, the processing circuitry executes the out-of-vehicle notification based on the distance between the host vehicle and the another vehicle, 
 when the distance is equal to or smaller than a first threshold and equal to or larger than a second threshold that is smaller than the first threshold, the processing circuitry executes the out-of-vehicle notification, and 
 when the distance is smaller than the second threshold, the processing circuitry does not execute the out-of-vehicle notification or executes the out-of-vehicle notification with a notification intensity lower than that when the distance is equal to or smaller than the first threshold and equal to or larger than the second threshold. 
 
     
     
       2. The control device according to  claim 1 , wherein
 the headlight is switchable between a first state and a second state in which the headlight is able to illuminate farther than in the first state, and 
 the out-of-vehicle notification is headlight flashing in which the headlight is switched between the first state and the second state at a predetermined cycle. 
 
     
     
       3. The control device according to  claim 1 , wherein
 the another vehicle is a vehicle that travels in the opposite direction to the host vehicle and at least a part of which is on a travel lane of the host vehicle. 
 
     
     
       4. The control device according to  claim 1 , wherein
 when the another vehicle is detected in front of the host vehicle and a curvature of a road on which the host vehicle travels is equal to or larger than a predetermined value, the processing circuitry executes the out-of-vehicle notification based on the distance between the host vehicle and the another vehicle. 
 
     
     
       5. The control device according to  claim 1 , wherein
 when the another vehicle is detected in front of the host vehicle and a travel speed of the another vehicle is equal to or larger than a predetermined value, the processing circuitry executes the out-of-vehicle notification based on the distance between the host vehicle and the another vehicle. 
 
     
     
       6. The control device according to  claim 1 , wherein
 when a predetermined period has elapsed since the out-of-vehicle notification is started, the processing circuitry ends the out-of-vehicle notification. 
 
     
     
       7. The control device according to  claim 3 , wherein
 when the another vehicle leaves the travel lane of the host vehicle after the out-of-vehicle notification is started, the processing circuitry ends the out-of-vehicle notification. 
 
     
     
       8. The control device according to  claim 5 , wherein
 when the travel speed of the another vehicle gets smaller than the predetermined value after the out-of-vehicle notification is started, the processing circuitry ends the out-of-vehicle notification. 
 
     
     
       9. The control device according to  claim 1 , wherein
 when a steering amount or a steering torque of the host vehicle gets equal to or larger than a predetermined value after the out-of-vehicle notification is started, the processing circuitry ends the out-of-vehicle notification. 
 
     
     
       10. The control device according to  claim 1 , wherein
 when a change amount of a yaw angle of the host vehicle from a start of the out-of-vehicle notification gets equal to or larger than a predetermined value after the out-of-vehicle notification is started, the processing circuitry ends the out-of-vehicle notification.
